-Combined with a blog, website or other content of adequate lengthYou can't put detailed information on these posts. You want to use these posts as attention catchers to lead people to another location that can be more easily found in the future and can carry the details--time, date, location, and so forth.-I post the detailed information on my virtual outworlding blog. Then I post key information on Twitter and Facebook, ending with the url. Facebook recognizes the url and formats it as a link to my blog. -As an announcement of an event about to start in Second LifeI use this method much as I use group chat messages inworld, posted near the time of the event This fits best with Facebook, so that is where I use it. I post a brief announcement, followed by a slurl. Facebook recognizes the slurl as a destination in Second Life and adds information telling about Second LIfe. Sometimes Facebook also adds a promotional badge inviting the user to join Second life by clicking on the badge. -In any case, someone not yet in Second Life can click on the slurl or the badge to and get an invitation to enter Second Life. If they follow the instructions, they will arrive at the event destination in a few minutes. Since they will arrive using Viewer 2.x. they will arrive with media and voice working (most of the time).
